A felling wedge is inserted into the cut when felling a tree, to guide the fall and keep the trunk from pinching the saw bar. Polyamide does not damage the chain if the saw accidentally touches the wedge. The 5" size is given in the name.
Replace the wedge if it has splits or deformation: a cracked wedge can pop out of the cut. Use it together with protective equipment and observe safe felling practices.
